I recently purchased the dvdfab as well. I too, am having the error 116 dvd failed to burn message. It only seems to happen when I am burning full disc not when I burn main movie only. I am using Memorex DVD+R DL discs for full disc and the same for main movie when needed for space, otherwise I just use DVD-R TDK's. So, I don't think it is the brand of discs I'm using. I need serious help! Can someone please help me?
